I don't think sticking it on the power brick is a good idea. You're far more likely to lose that than the laptop at which point unless you're a packrat and wrote it down somewhere else (99% of users won't) if you need to reinstall windows you're SoL.

For that matter, I thought MS licensing reqs required sticking it to the computers primary chassis; which the power brick is not.Reply

Yeah, it is a little questionable, but considering OEM machines ship with restore partitions/DVDs that put an activated copy of windows on the hard drive, the COA is only there to make you feel warm and fuzzy. Even if you want to install a clean version of Windows 7, it's just as easy to use ABR to backup and restore the key on the machine.Reply

ASUS notebook does not need Windows Product key for installations. The licence number is embedded in hardware itself and the product key is never typed during OS recovery.Losing the COA does not stop your from reinstalling OS at all.Reply

I own the UX31E. I see in the BIOS and in the driver stack there is support for a TPM chip. When you opened this up did you see a spot for a TPM chip. I will buy one and sodder it on myself if its reachable. Reply

This is the only Zenbook teardown I could find online, and since it said a torx T2 was used, I spent all day Friday trying to get one locally. The smallest size Home Depot and other hardware stores had was T4. I finally found someone who had a T3 and borrowed it from him. The T3 was too small; it just spun around in the screwhead and did nothing.

His next size up in the kit was a T5 and it worked fine on the Zenbook's screws. Due to the small amount of play with the T5, I'm guessing a T6 will work fine (but I don't have one to test with). T6 is the same size Macbook Pros used to use.

I'm glad I didn't just order a T2 online and wait for it to arrive, because it wouldn't have worked at all.Reply
